This gallery contains the best of the Chemistry Cat meme. Rumor has it that the image that started it all was an old Russian stock photo. Caption your own Chemistry Cat using the Chemistry Cat Caption Generator at memegenerator.net. Chemistry Puns Best of Chemistry Cat Chemistry Cat is in his element when it comes to chemistry puns. Public Domain Chemistry Cat: Chemistry puns? I'm in my element. Explanation: Chemistry is the study of matter and energy. The simplest building block of matter is the atom. When the number of protons in an atom changes, you have a new element. Prephosphorus! Best of Chemistry Cat Chemistry Cat claims he doesn't enjoy chemistry jokes. Public Domain Chemistry Cat: Most people find chemistry jokes funny. I find them prephosphorus. Explanation: Prephosphorus = Preposterous. Phosphorus is a chemical element. (Just in case you did not get it...) Tungsten Joke Best of Chemistry Cat Chemistry Cat has another on the tip of his tungsten. Public Domain Chemistry Cat: I know there's another chemistry joke...it's on the tip of my tungsten. Explanation: Tongue = Tungsten... Periodic Table Best of Chemistry Cat Chemistry Cat is occasionally on the table. Public Domain Chemistry Cat: Chemistry cat does it on the table, periodically.
